  4. Web 2.0's introduction of dynamic and interactive web apps improved user experience by introducing functions like drag-and-drop capabilities and tailored information delivery.
  5. Expertise democratization: Web 2.0 democratized information sharing by allowing a wider range of people to publish, access, and exchange various viewpoints and expertise.
  6. Centralized platforms: Web 2.0 was characterized by the dominance of centralized platforms that facilitated user interactions while exerting control and monetizing user data.
  7. Limited user data control: Users had limited authority over their personal data on Web 2.0 platforms, resulting in data privacy and ownership concerns.
  8. Interoperability challenges: Web 2.0 faced limitations in terms of standard protocols and seamless integration, hindering the exchange of data and services across different websites and applications.

Limitations and Challenges of Web 2.0:

Centralized control: The dominance of centralized platforms in Web 2.0 raised concerns about data control, privacy, and the concentration of power in the hands of a few entities.

Limited data ownership: Users had limited control over their data on Web 2.0 platforms, with platform owners collecting, storing, and monetizing user data without clear consent or transparency.

Data privacy concerns: Web 2.0 raised significant concerns about data privacy as user information could be accessed, shared, and used for targeted advertising or other purposes without explicit user consent.

Filter bubbles and echo chambers: Web 2.0 algorithms often created filter bubbles, exposing users to content that reinforced their existing beliefs, and limiting exposure to diverse perspectives.

Interoperability limitations: Lack of standardized protocols and interoperability between Web 2.0 platforms made it challenging to seamlessly share data and services across different websites and applications.

Digital divide: The adoption of Web 2.0 technologies created a digital divide, excluding those without reliable internet access or technology from the benefits and opportunities of the interactive web.




Introducing Web 3.0

Web 3.0, the subsequent iteration of the internet, ushers in a fundamental shift in how we communicate and transact online. 

Decentralization, blockchain technology, and trustless networks are some of its guiding concepts. With less reliance on centralized middlemen, Web 3.0 anticipates a time when consumers have more control over their data.

It encourages peer-to-peer connections, allowing people to converse and exchange with one another without the need for a middleman.

Transparency, security, and immutability of data are crucially supported by blockchain technology. Web 3.0 aspires to make online spaces more welcoming and equal while also fostering user empowerment and digital sovereignty.


Key features and technologies associated with Web 3.0

  • Web 3.0 depends on blockchain technology, which makes data storage and verification decentralized and transparent.
  • Self-executing agreements, or smart contracts, establish confidence and streamline procedures by doing away with middlemen.
  • Running on dispersed networks, decentralized apps (dApps) provide improved security, privacy, and censorship resistance.
  • Web 3.0 promotes tokenization, in which digital assets and tokens stand in for physical or virtual goods to make ownership and trade easier.
  • Privacy and data control: Web 3.0 reduces the need for middlemen by giving consumers more privacy and control over their data.
  • Enhanced security: Web 3.0 improves security and decreases vulnerabilities by utilizing blockchain and decentralized networks.
  • User-centric approach: Web 3.0 fosters a user-centric internet, giving individuals ownership and sovereignty over their digital presence.
  • Transformation of information and value exchange: Web 3.0 transforms how information and value are shared and exchanged online, disrupting traditional systems.
